Precast, Prestressing & Post-Tensioning Technology - Nirajan Kumar Jha

Résumé :
First, we have to understand what is precast concrete. Precast concrete can also be called readymade concrete or prefabricated concrete. Following is the definition of precast concrete. The form of construction where concrete is cast in a reusable mold and then cured in a controlled environment (a precast plant) is called precast concrete. The casted structural member is then transported to the construction site and then erected. Structural members such as concrete frames, concrete walls, concrete floors, etc. can be constructed using precast concrete. There are many precast concrete advantages. They are discussed below.1. Saves Construction Time: Precast Concrete construction saves time, and the risk of project delay is also less. The precast concrete casting can be carried on simultaneously with other works on site such as earthwork, survey, etc., and thus saves time. It is a major advantage of precast concrete. 2. Quality Assurance: The key factors which regulate the quality of construction such as curing, temperature, mix design, formwork, etc. can be monitored for pre-cast concrete. So, improved quality construction can be performed. 3. Usage of Prestressed Concrete: By using pre-stressed precast, structural materials of high strength and load-bearing capacity can be achieved, which can result in greater clear span, reduced size of the cross-section of structural members, etc 4. Cost-effective: The simplified construction process reduces time and increases productivity, quality, and safety and thus the cost is reduced. 5. Durability: Precast Concrete structure has a longer service time period and minimal maintenance. The high-density Precast Concrete is more durable against acid attack, corrosion, and impact, reduces surface voids, and resists the accumulation of dust.)

Biographie:
Mr.Nirajan Kumar Jha has worked on Ten Precast Mega projects in different countries e.g Barwa City housing Project, Cricket Stadium, Football Stadium, and Doha marine project in Doha, Qatar. King Faisal University and National guard house project in Saudi Arabia. Kanombe Military Barracks Project and Batsinda Housing Project in Rwanda, East Africa. Leisure Valley Project and Verona height project in India. I have gained very strong experience in Precast construction as well as very strong relationships with many clients and suppliers who work in many fields and industries to do with Precast construction and manufacturing. I am currently serving my duty as an Erection Manager in Afriprecast Mailbridge holding group in Rwanda, East Africa. My personal attributes include leadership and sound judgment as well as creativity, analytical and troubleshooting skills. I interact productively with people from diverse backgrounds. As a Civil Engineer, I am interested in taking on greater challenges and each responsibility I have and I would welcome the opportunity to meet. I have written my first book name Precast Concrete Technology (Future of Civil Engineering) in 2017. This is my Second Book.)
